Mine were already decorated with fondant, but I would think you let it get back to room temp, which happens really fast, then frost. I took mine out and let them thaw on thr counter, but that is just because I was worried about moisture on the fondant. I am not sure what others do, maybe someone else will chime in. Good luck, but I think either way would be fine.
